Invented by the native Alaskan people over 5000 years ago, the Alaskan ULU, was used primarily to clean and skin fish. Today, people find them very useful in the kitchen for cutting and dicing and also out in the field. Originally the handles were made of bone, ivory or wood inscribed with distinctive designs, but today many materials are available to use on the handles. Use your imagination, and make several. We carry two styles of blades to choose from. They are stainless steel, high carbon, mirror polished blades 0.056" thick with 6" cutting edges and oversize 3/16" holes. These blades have been CRYOGENICALLY TREATED to increase their edge holding properties.
